MACHINE. FOR CORRU GATING AND FACING PAPER.

SPECIFICATION forming part of Letters Patent No. 545,354, dated August 27, 1895.

Application filed February 21, 13

To all whomit may concern:

Be it known that I, JEFFREY T. FERRES, residing at Anderson, in the county of Madison, State of Indiana, have invented certain newand useful Improvements in Machines for Corrugating and Facing Paper, of which the following is a specification.

One object of my invention is to provide a combined corrugating and drying drum of such dimension that the paper is corrugated, pasted, set, and dried in the teeth and grooves which form the'corrugations.

Anotherohject of my'invention is to provide proper means for distributing air-currents across the paper dryingv both edges alike while seated in the corrugations.

Another object of my invention is to provide proper means for pasting on a second sheet of paper when it is desired to make a double-faced corrugated paper, with proper means for circulating air-curren ts for quickly and evenly drying the same and giving it a smooth calendered surface. Heretofore it has been necessary to use a certain grade of paper dried just right, so as to retain the impression giv'enit by the corrugating-rollers until it is carried forward and pasted to the sheet forming the face, and as the paper on a damp-day would not retain the impression as in dry weather the result has been a product in which the corrugations were not all alike; but in my machine the sheetlforming the face is pasted to and dried on thecorrugate'd sheet while it is held by the corrugating-roll, retaining the precise shape given it by the said roll; als0,in using currents of air more or less heated as an auxiliary fordryingithas been customary to exhaust or blow the air through the corrugations or across the paper from one side only. As such a method tends to dry one side more than the other, itcan be readily seen that an inferior product would be the result. My invention obviates this objection bydrying both edges, of the paper evenly and continuously.

The various features of my invention will be more fully set forth in the description of the accompanying drawings, making a part of this specification, in which- Figure 1 is a centralverti'cal section of the machine embodying my invention. Fig. 2 is a top plan view of a modification of the past- Serisll l'o. 639,304. (Remodel-l ing-rolls. Fig. 3 is a section on line mm, Fig. I 2.

Fig. 9 is a broken sectional elevation of the corrugating-drum. Fig. 10 is a detailed face view, of Fig. 9. Fig. 11 is a modification of Fig. 9. Fig. 12 is a sectional face view of Fig. 11.

A represents the main frame of the machine. g 1

B represents the frame supporting the secondary supporting, pasting, and drying app'aratus.

arepresents the shaft supporting thecorrugating and drying drum 0. This shaft is drum is provided with cogs or teeth running transversely across the face of the drum.

D represents the coacting corrugating-roll provided with similar cogs or teeth meshing with those of the drum 0.

D represents the roll of paper to be corrugated. .This paper (1 passes around the idlerroller cl and thence between the cogs or teeth of roll D and drum 0, which corrugate or flute the paper. In order to prevent the corrugated paper from rising on leaving the corrugating-drum C, a series of belts C are provided, and they run in circumferential grooves pierced in the roll. D. Said belts extend upward and forward around the paste-roll E, which is likewise provided with a similar series of circumferential grooves, thence over the idler-roller X. The roll E coactswith the pasting-roll c to spread thepaste upon the corrugated paper for attaching the first of lining or facing paper a.

e represents the pasting-trough, into which lhepasting-roll e dips and spreads the paste upon roller E.-

In order tohold the'corrugated paper closely in contact with the drum for the major part of its revolution, I provide the following in until wholly or partially dried, and likewise holding the contact of the corrugated paper with'the corrugating-drum until the corrugated paper is set and dried in the corrugations, and also forms the top of air-ducts between the paper and the orifice where air is taken from the interior of the drum. In order to facilitate the drying, I provide the following instrumentalities: The grooves h in the face of the drum 0 are closed at one'end and provided with an orifice h, leading from the interior of the drum, whereby a current of air is admitted into one end of a corrugation in the paper and compelled to pass across through the corrugation and escapes at the opposite side, as shown in Fig. 9. These orifices are arranged in each groove alternately at opposite ends of the drun1,so that the current is opposite in directions in each alternate corrugation. k represents a series-of orifices at one end of the drum and h at the opposite end of the drum. In this form of construction the belt G is made broad enough to cover the orifices h and rest upon the face c of the drum. Instead of constructing the orifices in this form I have shown a modification in Fig. 11, whereby the orifices are carried horizontally through the filling-piece c and opened into the corrugations h, the opposite end of the drum being provided with alternate passages in the opposite direction. In order to regulate the depth of the corrugation, roll'D is supported upon links 1, which are yoked together in any appropriate manner and pivoted on the center of idler-roll d. J represents a pressure-bar controlled by springj. K represents nuts for adjusting the inclination of links 1, so as to move the roll D to or from the corrugating-drnm and thereby regulating the depth of the corrugations. I

When the single-faced corrugated paper has leftthe corrugating and drying drum 0, it

maybe continued on through the endless.

aprons N O to still further dry it, or if it is desired to face the opposite side of said corrugated paper I provide the following ins't1'u mentalities: L L represent a second set of pasting-rolls, and Z' the pasting-trough, which parts are similar in construction to rolls E e, but not having any circumferential grooves as there are in roll E. As the'paper passes between the rolls H L, it; receives the paste from the latter roll and thence passes under.

the roll M, where it is brought into contact with the strip of paper m from the roll m.,

In order to support the corrugated paper againshsuitable pressure brought upon the strip in to cause it to adhere and thence to dry it, I provide the following instrument'ali: ties: N represents an endless chain passing over sprocket-wheelstt-n'. 0 represents a similar chain upon the sprocket-wheels o o. P P represent lags-pivoted to the sprocketlinks Q by the ears p and bolts P Said chain may be of any suitable kind adapted to run on sprocket-wheels with a suitable number of links provided with attachments, so that the lags P may be pivoted at or below the center at the end of said attachments, thus forming an endless belt or apron. The upper endless chain 0 depends and rests upon the face of the paper, which is supported in a horizontal position by the chain N. The

weight of the chain and lags is suflicient to press the facing-sheet upon the corrugated paper and hold it in that position until it is dried or set. i

In order that the paper may be properly dried, I provide the following instrumentalities: S S represent a series of jet gas-burner pipes, as shown in Fig. 7, supplying heat to the under side of the lags of the sprocketchain. 1 also use a set of air'pipes 'l T, through which a current of air is blown, and in order to have the paper dried uniformly I arrange a series of orifices t t at; alternate intervals, each series of jets in one set being opposite the space between the jets of the pipe at theopposite side of the paper, so that a current of air is blown in each direction alternately through the corrugations of the paper as it is carried along between theendless aprons. I

As a measure or chcapness and cconom y it is sometimes desirable to paste only sections of the facing-paper to the face of the corrugations. When this is desired,I place on the paste-trough Z a scraper u, one end of which is secured to the trough and the opposite end engages with the face of the pasting-roll L, thereby removing the paste from the section or sections ofv said roll which the end of the scraper comes in contact with. Of course as many scrapers or sections of scrapers are employed to engage with the face of the pastingroll as are desired.

As it would assist the drying of the paper materially to use heated air in the drum 0 and pipes T, it is optional with me whether the air is heated before its introduction into the drum 0 and pipes T or heated in them by steam-pipes or other well-known means.

In Fig. 7 w represents a metal plate interposed between the burners S and the lags of apron N to prevent the paper from being burned.
